Grand Theft Auto IV Walkthrough

Head to Alderney, where Hardtack Avenue and Lee Road intersect with one another. Nearby (as seen on your HUD), you can find a guy named Derrick lying on a bench in the park, drunk and doped-out. Speak with him, and he'll soon come to his senses, asking Niko to help him out with a mission of retribution. Niko seems to have a soft spot for this drunkard, and agrees to help him out (not to mention he's related to Packie, Kate, and others, so...). And just like that, yet another new contractor sends you out on your way.

Your first order of business is to find a cop car, because you're going to need to access a cop car's computer. As you certainly know by this point in the game, there are hard ways to do this and there are relatively easy ways to do this. If you're not using cheats (and you shouldn't), finding a parked cop car which you can break into is optimal, but there's another way if you're having problems. Find a cop car and bump it with your own car. This will cause the car to stop and the cops will get out. Then, jump into their car and speed away. This should only leave you with a one star wanted level that you can easily lose.

Once you have a cop car and have lost any wanted level you may have accrued, access the computer and look up the name the game prompts you to check out -- Bucky Sligo. After looking this criminal up, you'll find out that his hang out is over at a branch of the Burger Shot chain at the far north end of Alderney, where Owl Creek Avenue runs into Sacramento Avenue. Head over to that location after adding it to your GPS, and watch as Bucky runs off to find his friends and protect himself from arrest, just as Derrick hypothesized. Keep in mind that you need to keep your cop car after looking him up in order for this to work. He has to think you're the cops, not just some dude.
